invention relates to a centrifugal ex-, tractor, particularly for laundry use, and comprising a basket rapidlyrotated in a case having a hinged cover permitting access to 5 the basket.

The chief object oithe invention" is to r .v

'vide improved mechanismfor preventing the possibility of injury to the hands of the operator by the rotation, of the basket, particularly when the latter is rotating by its own momentum, after it has been disconnected from the source of drivingpower. b t Other objects will hereinafter appear. i 7

I In the drawings, :12 deslgna tes the fixed 1 case of a centrifugal-extractor; and 13desig-- hates theusual rotary basket within the case lfixedto'a vertical basket-shaft 14,-whichis driven byaftransinijssio'n' belt 15, "running,

16s a transmission pulley l6, and an idle pul ley 17. Thepulley'ltl is' fixed to' a power driven countershaft18provi dedwith the usual'fast pulley 19, and; loose pulley 20,.on either of which the driving belt 21 may run,

' being transferable y a Shipper the operator. Of the accompanying drawings forming a part of this specification, j a

i v v Figure '1 is'a top plan view of an extractor attached to-a shipper rod 23, which is movable as usual, in fixed guides, by a shipping lever composed of a hub portion 24, an arm 25 secured to the shipper, and an. arm 26 con- 7 stituting a handle whereby the operator may locate the driving belt on the fast pulley 19, to cause the rotation of the basket, and on the loose pulley 21' to disconnect the basket from the sourceof power.

i'llhe case-12 is provided with a cover 27,

connected by a, hinge 28 with the top of the case and adapted tobe openedand closed by I provide the mechanism next described for locking the cover closed and preventing it from'being opened by the operator while the basket is being rotated, either by power, or by itsi own momentum, and for preventing the operator from starting the rotation of the basket whileth'e'cover is open. The cover 27 is provided at diametrically jopposite points. with cars 29, spaced equally from the hinge 28, and adapted to be engaged simultaneously by detents 31 and 32, to hold the cow'ferclosed; Said'detents are fixed to the outer ends of flexible rods, each composed of [links 33 and 34 Figures 7, 8 and 9) jointed tojea'ch other by pin s 35, the rods being adapted to conform. to the curvature of arcuate tubularfguides 36, fixed'to the top of the case.

To the inner ends" of the flexible rods are attached non-'flexibleextensions 37, projecting I from the guides 36, and connected by links 39 with an arm 40 fixed to an operating rod 41,

' which is longitudinally movable by the mechanism hereinafter described, to movethe flexible rods en dwise in the guides 36, and there-' by simultaneouslyengage the detents31 and 32 with, and disengage'them from the cover rears 29, each detent being'alternately pushed amt pulled, and each being moved in the oplposite direction from the other. In this in stanc'e'the' detent 3lis straight and adapted "to be p'roj ected across one of the cover ears 29, as shown by Figures'l and 6, by an outward "en'dwise niovementof the flexible rod to which it is attached, while the detent 32 is hooked, andadapted to be projected across the other cover ear, as shown by Figures 1 and 6a, by

aninward endwise movement of the other i. end ofthe rod 41; and movesaid rod in the direction required to lock the cover. Said rod lhe 'arrangement such that j endvvise in the opposite direction, the de when the. operating rod 41 is moved endvvise V one direction, the detents .31 and 32 are" movedsimultaneously in opposite directions into engagement With theicover ears 29, to lock the cover and When'said rod is moved tents.are'movedsimultaneously in opposite directions, out of engagement with the cover ears to unlock the cover. e i i I The operating'rod 41 ismoved endwisein fixed guides 42by an angularmember desig- 41 the directionjrequiredto lock 4 the cover. Said'angular member is secured to the hub 24 oftheshipperlever by {a bolt 82 has an arm 83 With oppositelydisposed ears 84, B4, engaging theedges ofjthe shippers arm-'25, so} that when the shipper lever is niovedto conneotthefbasliet the. sourceof power; the arm 25' will act to move the angular member, andcausethe arm 81 thereof to engage rodis maintained in position tojloclz'thecover "by automatic means including a centrifugal agovjern'or 'vvhicln when; driven by the I means presently described-,iacts tokee p the rod lockingjvposition, and is 'movable by a-aspring 43 (Fignres l, 3"and1lO) whichfacts. to move the operating rod in the directionireqnired {to unlock the cover "when the povverjhas been :disconnectedand'the governor is atrest;
